TTC and not working

Katt
Okay so my boyfriend/fiancé (he is about to ask and we've talked about it for a while) and I have been trying for about 6 months now, and still haven't gotten pregnant. He told me it will happen and has just been so positive about it. I on the other hand am not taking it well. Especially when my mom tells me she had me so easily on the pill plus my brother as well. I just need some positive thoughts or ideas on what to do.
